T0 all whom t may concern.'

Be it known that we, PAUL A.. DRUGKLIEB, a citizen of the United States, and a resident of Stapleton, in the county of Richmond, State of New York, and DANIEL HEMMING, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, and whose postofiice addresses are both 14 Park Place, in the city,county, and State of New York,have invented certain new and useful Improven ments in Machines for Seaming Cigarettes, of which the following is a specification.

The object of our invention is to provide a device, simple and efficient in itself, which can be readily attached to machines of almost any class for the manufacture of cigarettes, without involving any material change or alteration in those machines; and which invention consists in means for laying down or finishing the pasted seam of a cigarette rod, without the use of heat applied, by preferably applying the finishing pressure only to the seam, or to it and those portions of the paper cover which lie immediately adjacent the lap of the seam, and eliminating pressure from that portion of the cigarette rod which lies outside of the plane of the seam, and which will perform these and other desirable functions satisfactorily without tearing the paper or' producing tucks or puckerings therein; and which will also produce in having a small lap, which is highly desirable. These objects are accomplished by means of our invention, one embodiment of which will be hereinafter more particularly set forth.

For a more particular description of our invention, reference is to be had to the accompanying drawings forming part hereof.

Figure 1 is a plan view of a portion of a cigarette making machine having our invention applied thereto. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is an enlarged longitudinal sectional elevation substantially on the plane of line 3-3 of Fig. 5, looking in the direction of the arrows. Fig. 4 is a still .further enlarged sectional elevation on the plane of the line 4:-4 of Fig. 3 looking in the direction of the arrows; and Fig. 5 is an enlarged sectional elevation on the plane of the line 5-5 of Fig. 3, looking in the direction of the arrows.

Throughout the various figures of the drawings, similar reference characters designate similar parts.

a At 1 is shown that portion of the hed of a cigarette making machine which lies in advance of the part which usually supports the means fo-r applying paste to the laps of the cigarette rod.

.As it must be assumed for the purposes of this description of our invention that the rod a comprising the tobacco filler b and inclosing paper strip c has been completed and the paste applied to the laps (Z, c, which forms the seam f, by any appropriate device, we do not think that it is necessary to illustrate such a device, and consider that it is only necessary to state that by the time that the cigarette rod has reached the means for finishing the seams, which is the subject matter of the present invention, that the paste has be/en appropriately applied and the edges of the strip c lapped to form the seam. rlhe finishing device herein disclosed is preferably located, so as to secure the best results, adjacent the pasting device, so that the paste will not have had time to dry, spread or set through absorption or pressure before it reaches the seam pressing portion of this device.

The bed 1 is provided with a groove 2 of the desired shape to support the cigarette rod and which forms a continuation of the groove through which the partially completed rod runs.

At 3 is a continuous tape or band, which constitutes means for conveying the rod, which tape or band passes over a pulley wheel 4, all operating in the conventional way to propel the cigarette rod, the direction of its movement being indicated generally by the arrows in Fig. 3.

At 5 is the bed plate of our finishing device. It may be secured upon the bed plate 1 by any desired means. As it is intended to be readily attachable to or detachable from machines of conventional structure its rear is provided with a dovetailed portion 6, so as to preserve its proper alinement. Its under surface is provided with a groove 7 which forms with the groove 2 in the bedplate 1, a tube receiving and confining the tape 3 and cigarette rod. Itis also provided with a recess 8 to allow one edge of the tape the design of this invention, its operative cross sectional area (as indicated at g, in Fig. 4L) should be preferably no greater or but slightly greater than the width of the seam,

Yas shown in Fig. 4, whereby a maximum elficiency is obtained with a minimum disturbance of the contained tobacco or the paper covering the rod. It will be noted hereafter, that this presser'blade is mounted, so as to eXerta regulatable and gradually increasing Y pressure on the seam in the directionof its length. To secure these results, we have devised a simple construction, which may be accommodated to the plate 5, or any like or suitable 'part of a cigarette making Vmachine, or which may be a fixed part of the Yplate 5 itself. This construction consists of the following elements: At 10 is a bearing block pivoted uponV a pin 1l, one end of which is secured to the upright portion 12 of an' angular plate 13, the horizontal portion 14 ybeing securedon the plate 5 by screws l5, the enlarged head 16 ofthe pivot bolt ll pressing the pivot. block 10 against the part l2 with a working fit, preserving the parallelism of the block 10, and coincidently theV presser bladeY or foot, which'is supported thereby, with the seam f, of the cigarette rod. The rear end of the blocklO is provided with a bore 17`threaded to receive an adjustable plug 18, against Ywhich plug bears the upper end of a spiral spring 19, the lower end of the spring resting upon the plate y5. The forward end of the block l0l is provided `with jaws 20, between which V'eX- tend a detachable screw 21, the heel 22 of the presser-blade 9'being held in'and secured tothe block by said screw 21, and between the jaws 20, thereby providing means for readily attaching or detaching the blade 9 and keeping it perpendicular to the seam ofY the cigarette rod. Between the jaws 2O and pivot pin 11, a set`screw or stop 23 is inserted perpendicularly to the block 10, its Y The lower end bearing on the block'. spring 19 furnishes means for keeping the operative surface of the presser blade yieldingly in contact with the seam f, the threaded plug 18 providing means for varying the tension of the spring and consequently tithe amount Aof pressure exerted by the Y eo presser blade on the seam. VThe setv screw-23 provides means for regulating thefinclina-VV tion of the presser` blade relatively to Vthe cigarette Vrod and its seam, and incidentally, the plane Vor extent of contactwhich itsop- Verative surface g may have with the seam.V

As constructed and shown here, the cigarette rod, freshly pasted and with its lap closed moves in the direction indicated by the arrows in Fig. .3, and the presser blade pressed downwardly by the spring 1 (and suitably adjusted Vby the set screw 23) contacts with the same at the lower heel24 hereof, andthe toe 25 of the blade 9 has decreased the diameter of the rod to the' extent of its inclination, theV depression of the rod where theV presser blade is thus brought into contact with theseamY being indicated by the dotted line 26; the contactv of the-presser blade withcthe seam and the pressure eXertedthereby being regulatable and gradually increasing in the direction of the length ofthe seam. The result of this,among f other things, is that the freshly pasted seam is adequately pressed, the presser foot dries Y. Y

the presser foot ,j which latter pressurev on the seam for a substantial dista-nce, keeps 'Y Vthe seam wellironed, lays it flat, and pre-Y i Y vents it from puckering.v During this Operation there is substantially no disturbance of theV contained filler, as shown inF t. V The adaptability of our improvements to machines already constructed, its simplicity `and compactness,1its freedom "from intricate parts requiring constant adjustment and attention, are all valuable points in its favor.

it: is, therefore, manifestthat our invention i may be embodiedin astructure differingV from that disclosed herein without departing from the-spirit thereof. i Havingjdescribed our'inv'ention, we claim :VY l. InV a vcigarette finishing machine, the
